It is the process of heat energy that electroluminescent heating process refers to electric energy conversion: when certain voltage is applied on resistance, produce certain electric current, and the product of voltage and current is then corresponding electrical power.In electrical resistance, when electronics does directed movement under electric field force effect, constantly can collide with metal ion, during collision, a part of kinetic energy be passed to ion, the warm-up movement of ion is aggravated, cause heating.The efficiency transformed follows Joule law.Electroluminescent heating element in the market has Electric radiant Heating Film, electric ceramic, electrothermal quartz tube, carbon fiber etc., and they are used to make electrothermal device miscellaneous and equipment, meet various different demand.Above-mentioned all kinds of electrothermal component has a common ground, and they are all the principles based on resistance heating power, by the heat energy produced via resistance wire, are delivered to surrounding environment, reach heating effect.Generally speaking, resistance-type heating technique has following general character:
Resistance material is usually in filament shape, very little with the contact area of external environment, and namely during energising, heating is very little with the area of heat radiation.The heat energy overwhelming majority that this makes resistance material produce is confined in resistance material body, only has seldom part to output to external environment by limited surface.Therefore, although resistance material can produce a large amount of electrical heat energies, it is lower that heat energy is exported the efficiency being delivered to surrounding environment by it.
As pure resistor load, its electrical heat energy produced does not change with the frequency of voltage, which has limited some application of resistance-type heating.
The relation of resistance wire voltage and current follows Ohm's law, and electric current increases with voltage linear, only has at higher voltages, could produce suitable electric current, and resistance wire is generated heat.Therefore, resistance-type heating effectively can not provide heat energy under the condition of low-voltage.
